Monotonicity in asset returns: New tests with applications to the term structure,the CAPM,and portfolio sorts

Many theories in finance imply monotonic patterns in expected returns and other financial variables. The liquidity preference hypothesis predicts higher expected returns for bonds with longer times to maturity; the Capital Asset Pricing Model (CAPM) implies higher expected returns for stocks with higher betas; and standard asset pricing models imply that the pricing kernel is declining in market returns. The full set of implications of monotonicity is generally not exploited in empirical work, however. This paper proposes new and simple ways to test for monotonicity in financial variables and compares the proposed tests with extant alternatives such as t-tests, Bonferroni bounds, and multivariate inequality tests through empirical applications and simulations.     

Payment card rewards programs and consumer payment choice

By using a unique data set that contains detailed information about consumer payment choice and consumers’ attitudes toward each payment method, we estimate the effects of payment card rewards on consumer choice of payment methods. Our approach allows us to control for consumer heterogeneity. We find the effects of rewards to be statistically significant across five retail types. Our policy experiments suggest that for the sub-population who hold both credit and debit cards, removing rewards would increase their share of paper-based payment methods (i.e., cash and checks), measured in terms of in-store transactions, by no more than 4 percentage points.     

Locked Up by a Lockup: Valuing Liquidity as a Real Option

Hedge funds often impose lockups and notice periods to limit the ability of investors to withdraw capital. We model the investor's decision to withdraw capital as a real option and treat lockups and notice periods as exercise restrictions. Our methodology incorporates time-varying probabilities of hedge fund failure and optimal early exercise. We estimate a two-year lockup with a three-month notice period costs approximately 1% of the initial investment for an investor with constant relative risk aversion utility and risk aversion of three. The cost of illiquidity can easily exceed 10% if the hedge fund manager can arbitrarily suspend withdrawals.     

Tracking a changing copula

A copula models the relationships between variables independently of their marginal distributions. When the variables are time series, the copula may change over time. Recursive procedures based on indicator variables are proposed for tracking these changes over time. Estimation of the unknown parameters is by maximum likelihood. When the marginal distributions change, pre-filtering is necessary before constructing the indicator variables on which the recursions are based. This entails estimating time-varying quantiles and a simple method based on time-varying histograms is proposed. The techniques are applied to the Hong Kong and Korean stock market indices. Some interesting and unexpected movements are detected, particularly after the attack on the Hong Kong dollar in 1997.     

Contemporary public sector accounting research – An international comparison of journal papers

This paper provides a broad review of the public sector accounting research in recent years, including that undertaken in the US. An analysis of this research reveals a methodological distinction between research undertaken in the US (using predominately functionalist methodologies, accompanied by positivistic quantitative research methods) and that undertaken in the rest of the world (using interpretive and radical/alternative methodologies, with qualitative research methods). The nature, causes and consequences of this distinction are discussed. The paper concludes with an exhortation for PSAR researchers to explore multiparadigmatic methodologies in future research.     

Planning Histories and Practices of Circulating Urban Knowledge

This symposium creates and stimulates new dialogue and cross‐disciplinary exchange between planning theorists and geographers in researching the transfer of urban policy and planning models, ideas and techniques. The symposium challenges a restricted historical focus in much of the emerging geographical literature on urban policy mobilities by drawing on a rich tradition within planning history of exploring and documenting the trans‐urban travel of planning ideas and models over the last 150 years. It is argued that this longer‐term perspective is required to highlight important historical continuities and institutional legacies to contemporary urban policy circuits and pathways and to question what is particularly new, distinct and innovative about an intensification in the travel of urban ideas, plans and policies over the past decade — and the accompanying scholarly interest in them. The symposium also uses the emphasis on particular details and specific experiences within planning histories to foreground and develop approaches, particularly from recent geographical scholarship, that investigate the contingent and embodied practices and wider epistemic contexts that enable — or hinder — contemporary policy transfer.     

Membership,influence and voice: a discussion of trade union renewal in the French context

Union density in France has fallen to exceptionally low levels, yet unions are able to mobilise millions of supporters against government austerity measures. Some authors therefore argue that the union revitalisation literature overemphasises density over other power resources. The article first confirms the decline of density and the scale of the challenges unions face in organising in the face of restructuring and casualisation. Second, it is argued that unions have retained some policy influence by forming strategic alliances among themselves, although pressures for fragmentation remain strong. Third, unions' mobilising capacity indicates the need to find new ways of coordinating action at all levels. The article thus not only confirms the inadequacy of density alone as a measure of union vitality but also highlights the challenges, and some opportunities, facing unions in hostile economic conditions.     

Rent control according to Seinfeld

More than 30 years after its premiere, Seinfeld continues its run as a seminally popular television show. On October 1, 2021, five-year streaming rights to the show were purchased by Netflix for $500 million. Set in New York City, where rent control laws have a long history, several episodes of the show consider the trials of apartment living, including shortages, tastes for discrimination by sellers, bribery, search costs, and quality degradation. Seinfeld also illustrates the informal process through which rent-controlled apartments are advertised (e.g., less advertising under rent control shortage). This paper argues that popular media can be used as an effective pedagogical tool in learning. This paper analyzes four episodes of Seinfeld to help students identify and differentiate the very real costs of rent control. The paper also guides students to appreciate the difficulty in crafting a policy that is free of unintended consequences.     

Unpacking the client(s): Constructions, positions and client–consultant dynamics

Research on management consultancy usually emphasizes the role and perspective of the consultants. Whilst important, consultants are only one element in a dynamic relationship involving both consultants and their clients. In much of the literature, the client is neglected, or is assumed to represent a distinct, immutable entity. In this paper, we argue that the client organisation is not uniform but is instead (like organisations generally) a more or less heterogeneous assemblage of actors, interests and inclinations involved in multiple and varied ways in consultancy projects. This paper draws upon three empirical cases and emphasizes three key aspects of clients in the context of consultancy projects: (a) client diversity, including, but not limited to diversity arising solely from (pre-)structured contact relations and interests; (b) processes of constructing ‘the client’ (including negotiation, conflict, and reconstruction) and the client identities which are thereby produced; and (c) the dynamics of client–consultant relations and how these influence the construction of multiple and perhaps contested client positions and identities.
